Tube Saturator 2 is a super accurate circuit simulation of a tube pre-amp with analog EQ, which can be overdriven gently for warming effects, or cranked for fat distortion. Like its predecessor, Tube Saturator, TS-2 is based on circuit simulation techology to capture every nuance of an analog circuit. The circuit consisting of the individual tubes, resistors, and capacitors is converted into a mathematical system of equations which is numerically solved to produce the exact same sound as a real circuit. But while the original consumed large amounts of CPU power, TS-2 is now super efficient. The Saturation section of TS-2 runs about 7x faster than the original and yet the modelling is even more accurate. TS-2 includes the original circuit simulation of the three band Baxandall type EQ as found in many guitar amplifiers.
